How tax filing works
Get started quickly.
File your taxes online, in person, or drop-off.
We are making it easier than ever to file your tax return. Either upload your tax documents using our encrypted client portal or drop them off in person at our office.
After you finish a brief tax interview in your client portal a licensed tax advisor will contact you with any follow-up questions they may have regarding your tax return.
When your tax return is finished, typically within 5-7 business days, you will have the option to either self-review or review with your tax advisor. This is the same tax advisor you will have access to year-round and work with as long as you are our client.

My wife and I own a couple rental properties, we never depreciated any of the homes and didn't know we were supposed to. Our tax accountant figured out our missed depreciation and fixed our taxes.

Working with Mraz Tax Solutions has been a great experience. They prepared my business tax return, helped me setup a payment plan with the IRS and calculated quarterly payments so I don't owe in the future.

I uploaded my documents to my tax preparer Milan. He prepared my taxes and when they were done, we reviewed them over video. It was easy and I didn't have to go anywhere or print anything.
